Last time Before install

Ok I have been looking for this answer for a long time now, and never came up with a clear one yet.

Ok I have [email protected] (NINe.2 )
I want to get either of these:Image Dynamics CXS64 (4ohm model)
(the 2ohm models have been on backorder for ever, and I cannot wait n e longer, install is coming soon)CDT EF61 (Silk tweeter)

Question:
Overall which would sound better throughout the music with 100wrms?
Which one will get louder with 100wrms?

Im just worreid that if I buy the ID's they will not get as loud as I want them to with only 100watts instead of the 150watts rms they recommend.
(the CXS's take 150watts, and the EF-61's take 120watts)

Honestly Which ones should I get, Install is this week! Please help ASAP!!
